vApplication ledl (ctober 9, 1911. Serial No. 653,638.

Be it known that I, ROBERT A. Gianni', a citizen of the United Stateaf-residing at Cincinnati, in the county rof Hamilton and State ofjOhio, have invented certain new and useful Improvements in Musical-lnstrument Bellows, of which the following -a specification.

means, the construction of which I` nowgset;

forth.

Figure 1 is a front view in section show# ing my special reservoir with tliel'accompanying pumps and pedals, Fig; 2 being the same bellows with the reservoir partly colf lapsed. Fig. -3 shows a modified position ol the spring inthe reservoir, and Fig. 4 is a vertical section taken at right angles to Fig. l.

My reservoir l, when at rest and during the first part of its motion, is of a square acting form with its moving board 2 and fixed board 3 substantially parallehsimilar to that of a pipe-organ; but during the second part of its motion, owing to the inten. yruption of the motion of one end of the movable board 2 by the block 4 or equivalent interrupting means, the'movableboard 2 acts in the hinged manner of a reed organ or V bellows from the fulcrum of the block 4 at the interrupted end of the board 2.

The spring 5 opposes the motion of the board 2 at all parts of the motion of that board, being preferably applied midway between the two ends of said board, so that its action is without change of air tension as the mot-ion of board 2 changes from parallel action to hinged action. Then a decided change of tension is desired from t-he one motion of the board I2 tothe other, the spring 5 may be placed away from the midway position, as shown in Fig. 3.

-a'rious other arrangements of spring means'inay be combined lwith my interrupt- I otmy invention.Y

ing means wit-heut departing from the spirit To suit the varied requirements of air supply forv di-.t'erentt musical compositions or the personal preference of different users, a manually `co'ntrollednneans can be employed to throw the interrupting means 4 in 4or out oi' engagement position with the movablef'board 2, as by link 6, crank shaft 7 and handle 8. *l-Then no throwont means is desired, the interrupt-ing block 4 can be most ecoi'iomicaliy placed inside the reservoir l, as shown in Fig. l by the dotted lines 9, and in Fig. 3.

What I claim as my invention is:-

1. A musical instrument bellows reservoir having-a bodily movable board free to move at both ends during the first part of its motion, andineans adapted to interrupt the vmotionl Q, one end of said board during the .second part of its motion.

2'. A., musical instrument bellows reservoir fliaving ai bodily movable board 'free to move at both endsfduring the firstl part' of its motion, 'and vmeans adapted to interrupt the motion otfone end of saidboard during they second part of its' motion, and a spring means in opposition`lv to the movement vof said board during bothv parts of its motion.

3. A. musical instrument bellows reservoir having a bodily movable board free to move at both ends during the first part of its motion, and means adapted to interrupt the motion ot' one end of said board during the` second part of its motion, and a spring means in opposition to the movement ot' said board during both parts of its motion, said spring means being. opposed to said moving board intermediate the two ends oi' said board. t

' 4. A musical instrument bellows reservoir having a bodily movable board free to move at both ends during the first part of its -motion, and means adapted to interrupt one end of said board during the second -part of its motion, and a spring means in opposition to the movement of said board during both parts of its mot-ion, said spring means being opposed to said moving board interf mediate the two ends 'of said board and be' tween the interrupting means and the uninterrupted end of said board. l

ada Med te interrupt the motion of that end no of the movable board before the complete extent of motion of its other end. v

6. A musical instrument bellows reservoir having two substantially parallel boards, one'xed and one bodily. movable and collapsible, a covering around all Sides of said boards and ay block between the two Said boards, adjacent one end thereof', and less in dimension than the greatest distance between the boards at that place.

7. .5L musical nstrlunent bellows 'reservoir having a bodily movable board free to move' at both ends during the first part of its motion, and means adapted to interrupt one end of Said board duringthe second part of its motion, and manually controlled throw o means combined With Said interrupting means to throw said interrupting means in and out of operative position at will.
